Zusammenfassung:	PURPOSE: A wireless communication system transmitting frames of applications demanding quality of service and a method thereof are provided to more rapidly transmit a GTS request frame to a coordinator and to reduce the delay time to the arriving time of the GTS request frame to the coordinator. CONSTITUTION: A coordinator(200) is one among a plurality of sensor nodes(100). The coordinator synchronizes a plurality of sensor nodes. The coordinator performs the transmission control of data. The sensor node is connected to a WPAN(Wireless Personal Area Networks). The sensor node transmits and receives the data. The sensor node puts the priority on a waiting queue storing a GTS(Guaranteed Time Slot) request frame. When the GTS request frame is saved, the sensor node firstly transmits the GTS request frame to the coordinator more than a normal data frame.
